Pew Research Global Attitudes Project: report

There is a strong relationship between a country’s religiosity and opinions about homosexuality. There is far less acceptance of homosexuality in countries where religion is central to people’s lives – measured by whether they consider religion to be very important, whether they believe it is necessary to believe in God in order to be moral, and whether they pray at least once a day.
